ABSTRACT This study investigated the diet of laying hens containing selenium in organic, inorganic, and Se-Met complex encapsulated with chitosan was investigated in order to enrich eggs and their oxidative stability. The microencapsulation process was performed using two molecular weights of chitosan (150 and 250 kDa) and the ratio of chitosan to Se-Met (1:1.5 and 1:2) in order to achieve the best encapsulated selenium according to evaluation of particle size, zeta potential, and encapsulation efficiency. Subsequently, 450 Hy-Line W36 laying […]
